[osg-users] Getting the height of a 3DS node

[Adrian Jelffs]

Hello,

I am loading a 3DS file in to my scene and I need to find out the height of the object. I want to place some text above the object which moves with a fixed offset but I don't always know the size of the object.

I am currently loading it like this:

_myNode = osgDB::readNodeFile("adrian.3ds");
 
I thought I could do something like this but hf always returns NULL.

osg::ref_ptr<osg::HeightField> hf = osgDB::readHeightFieldFile("adrian.3ds");

float height = hf->getSkirtHeight();


Many thanks for your help!!

Adrian
